1. Puas muaj qib "Zoo tshaj" Bronze?
Cov Qib Bronze Ntsiab & Lawv Cov Kev Siv Zoo Tshaj Plaws
Cov khoom xyaw: ~ 85% Cu, ~ 10% Sn, ~ 5% Pb.
Lub zog: zoo machinability, zoo hnav tsis kam, thiab ductility zoo.
Qhov zoo tshaj plaws rau: Bearings, bushings, gears, thiab valve stems -cov ntawv thov kom muaj kev sib txhuam qis thiab kev ua haujlwm yooj yim.
Muaj pes tsawg leeg: ~ 85% Cu, ~ 10% Al, (yeem) Fe / Ni ntxiv.
Lub zog: Exceptional tensile lub zog (txog 900 MPa thaum tshav kub- kho), superior corrosion kuj (txawm tias nyob rau hauv dej ntsev thiab tshuaj hnyav), thiab siab hnav tsis kam.
Qhov zoo tshaj plaws rau: Marine Cheebtsam (propellers, hull fittings), industrial li qub, twj tso kua mis, thiab hnyav machinery qhov chaw -scenarios xav tau siab zog thiab durability.
Cov khoom xyaw: ~ 88% Cu, ~ 10% Sn, ~ 2% Zn.
Lub zog: Zoo corrosion kuj nyob rau hauv marine ib puag ncig, zoo ductility, thiab nruab nrab lub zog.
Qhov zoo tshaj plaws rau: Naval hardware, nkoj hulls, thiab offshore structures -zoo tagnrho rau dej ntsev.
Cov khoom xyaw: ~ 95% Cu, ~ 5% Sn, phosphorus (P).
Lub zog: siab qaug zog, zoo heev caij nplooj ntoos hlav zog, zoo hluav taws xob conductivity, thiab corrosion kuj.
Qhov zoo tshaj plaws rau: Springs, hluav taws xob tiv tauj, connectors, thiab suab paj nruag - daim ntawv thov xav tau elasticity thiab conductivity.
Muaj pes tsawg leeg: Cu-Sn-Pb (vary los ntawm qib), porous qauv.
Lub zog: Tus kheej -lubricating ( khaws cov roj), zoo hnav tsis kam.
Qhov zoo tshaj plaws rau: Plain bearings nyob rau hauv siab -ceev los yog qis -lubrication ib puag ncig (xws li, tsheb cav, kiv cua muaj).
Kev xaiv qhov tseem ceeb
Ua ntejtxhuas bronzerau siab zog / corrosion kuj.
Xaivphosphor tooj liabrau springs los yog hluav taws xob Cheebtsam.
Xaiv rauleaded tin bronzerau tus nqi-zoo, machinable qhov chaw (piv txwv li, bushings).
Xaivnaval toojrau kev siv marine lossis dej ntsev.
2. Puas yog Nickel pheej yig dua Bronze?
1. Raw Khoom Nqe Dynamics
Nickel (Ntshiab): Ib qho tseem ceeb hloov pauv hlau nrog lub ntiaj teb kev lag luam volatility. Nws qhov tsis txaus thiab xav tau ntau hauv cov roj teeb (EVs), stainless hlau, thiab cov khoom siv hluav taws xob ua kom cov nqi nce siab.
Bronze: Cov tooj liab-raws li alloy, nrog cov nqi khi feem ntau rau tooj liab (cov khoom tseem ceeb, ~ 80-95% ntawm tooj liab) thiab tin / zinc (me me alloying ntsiab).
2. Kev zam rau Txoj Cai
Siab -kev ua tau zoo bronze alloys nrog cov npib tsib xee tseem ceeb ntxiv (xws li, txhuas bronze nrog 5-10% Ni) tuaj yeem ncav cuag lossis tshaj tus nqi npib tsib xee. Cov ntsiab lus nickel nce cov nqi khoom, txo qhov sib txawv.
Cov khib nyiab lossis qis-qib npib tsib xee tej zaum yuav pheej yig dua li cov tooj liab zoo (xws li, aerospace- qib aluminium bronze), tab sis qhov no tsis tshua muaj rau kev lag luam- cov ntaub ntawv qib.
3. Tag nrho cov nqi txiav txim siab
Nickel yog ib qho nyuaj rau tshuab thiab fabricate tshaj li feem ntau bronzes (xws li, leaded tin bronze), nce nqi tsim khoom rau cov khoom tiav.
Bronze qhov zoo dua machinability thiab formability feem ntau txo tag nrho cov nqi tsim khoom, txawm tias cov khoom siv raw khoom nyob ze.
Cov ntsiab lus
Tsis muaj "zoo tshaj" qib bronze- kev xaiv nyob ntawm daim ntawv thov- cov kev xav tau tshwj xeeb (lub zog, corrosion kuj, thiab lwm yam).
Cov npib tsib xee dawb feem ntau yog kim dua li cov qauv bronze qib, txawm hais tias siab -nickel bronzes tuaj yeem nqaim lossis thim rov qab qhov sib txawv no.
